Words to know
Legal words from the lines above, in plain English.
- human review
- Company staff or contractors may read your messages or content, usually to check for rule breaking. For example, a flagged private chat with an AI can be read by a person at the company.
- sell or share
- Under California law, selling means passing your data to others for money or other value; sharing means passing it on for targeted ads. For example, letting an ad network use your browsing history in return for ad space counts as a sale.
- personal data
- Any information that is about you or can be linked to you, from your name to your phone's ID. For example, your email, your IP address and the list of apps on your phone are all personal data.
- service providers
- Outside companies that handle your data on the app's instructions, such as a cloud host or an email sender. For example, the company that stores the app's files in the cloud sees your data but only does what the app tells it.
- retention
- How long a company keeps your data before deleting it. For example, a policy might keep your messages for 30 days after you delete them, or for as long as it likes.
- limitation of liability
- A cap on what the company will ever pay you if something goes wrong, often only what you paid in the last year. For example, if a leak of your data costs you thousands, the most you may get back is a month's subscription fee.
- as is
- You get the service in whatever state it is in, with no promise that it works or will keep working. For example, if the app deletes your photos by mistake, it is not promising to fix that or pay you back.
- warranty
- A promise that a product will work as described; most apps say they make no such promise at all. For example, if a paid feature never works on your phone, a no-warranty clause says that is your problem.
- venue
- The specific court or city where any lawsuit must be filed, which may be far from where you live. For example, a user in Florida may have to travel to a court in San Francisco to sue.
- consent
- Your clear agreement to something, given by an action like ticking a box or tapping Accept. For example, a pop-up asking if the app may use your location is asking for consent.
- governing law
- Which country's or state's laws are used to settle any dispute, no matter where you live. For example, a user in Ohio may find the terms are judged under California law.

What does the app collect beyond what it needs to work?
Besides chats, Gemini can collect contacts, call logs, screen content, connected-app data, device IDs, and location.
Does it record your voice, face or body, and what happens to that?
Live audio/video and avatar face/voice recordings can be stored with your account. Improving models with audio is off by default.
Are your chats and uploads used to train AI models, and is that off by default?
Keep Activity is on by default and uses chats to train models. You can turn it off in Gemini Apps Activity. Temporary chats are not used for training.
Can employees or contractors read your conversations, and when?
Some chats are reviewed by humans to improve models. Turning Keep Activity off or using temporary chats stops improvement review, but safety review can still happen.
Are you profiled or tracked for advertising?
Google says Gemini Apps chats are not used to show you ads. Shopping via Wallet may still involve ads under Wallet settings.
Do they sell or share your data, and can you opt out?
Google says it does not sell personal information. Data is shared with reviewers, other Google services, and apps you connect.
What rights do they take over what you type and what the AI makes?
You keep IP in your content, but you grant Google a worldwide, royalty-free, sublicensable license that lasts as long as the content is protected.
How long do they keep your data after you delete it, and can you delete it in the app?
You can delete chats in Gemini Apps Activity. Default auto-delete is 18 months. Human-reviewed chats can be kept up to three years after you delete them.
Does it build a lasting memory or profile of you, and can you see, edit or turn it off?
Memory can use past chats to personalize. You can turn Memory off, use temporary chats, or delete a chat so it is not used.
Do they commit to basic security, and have they leaked data?
Not stated in the documents.
Is there a real age gate, and are teens protected?
Google Account age rules apply; underage users need a parent’s permission. There is no extra age-assurance process described here.
Will they tell you when the rules change, and is the policy specific?
The privacy notice is dated. Google says it will give reasonable advance notice of material term changes, with exceptions for new features and urgent cases.
Can they close your account without warning, and can you get your data out first?
Google says it will give advance notice when reasonably possible before taking action, and you can export content with Google Takeout.
If something goes wrong, who pays?
Services are provided “as is.” Google’s liability is generally capped at $200 or fees paid in the prior 12 months. Business users must indemnify Google.
Do subscriptions renew on their own, and can you get a refund?
Not stated in the documents.
If this app can act for you, does it warn you about scams?
